I believe the authors name was Lynn. i recovered the story a few years back on thewaybackmachine site? i cant remember the fan fiction site any more though:(

The story involves Nsync yet revolves around Justin. He develops a great online friendship with a girl named Stripes. While staying with Chris in a family cabin he journeys out to the woods, breaks ankle and is stranded. Just so happens "stripes" finds him unconcious brings him back to her home and takes care of him until the snow storm has cleared up. They dont know that theyre eachothers online buddies...

Does this ring a bell for anyone? i was thinking the title was Could it be or something like that. HELP!!
